Re: [PATCH 0/1] MR9716: mf: Don't crash if stream is null during sample request.

[Charlotte Pabst (＠CharlottePabst)]

It might very well be API misuse that only functions on windows by chance. We're talking about a custom sink implementation here. Seems like after calling IMFMediaSession::Start, all the application does is wait until the sink's media type handler obtains a media type (SetCurrentMediaType) before queueing the MEStreamSinkRequestSample event (not sure if that wait is even related to this problem).
